Scientists from Japan said the chemical is added to the fries in order to keep the cooking oil from frothing up.

When they tested that chemical on mice, scientists said, the mice regrew hair.
Scientists said this is the first time they have mass produced what they are calling "hair follicle germs" with this method.

The next step would be try it on human skin cells.
McDonald's has not commented on the study at this time.
